Totem uses a fullscreen window with a headerbar at the top, and without
this change, that headerbar has rounded corners, which look different
from a maximised window and let video content show through beneath.

There is no need to have every application log a warning when the
Wayland display server goes away, and we are using _exit instead of
exit elsewhere.
This is also what the X11 backend does (see gdk_x_io_error).

As we now refrain from sending the crossing events if there's an
implicit grab, those events must be sent on button release when
the implicit grab is broken.
Check the grab widget (both explicit and implicit) and check for a cursor
from the target widget up to this grab widget. If the target widget is
outside the grab widget, only the grab wigdet's cursor will be checked.
This also means that we have to ensure the cursor is updated on button
releases, as an implicit grab being deactivated must trigger a cursor
lookup from the target widget.
In these situations we must perform the "is it claimed" check before removing
the (touch)point, as doing so when the gesture is empty will be too late if
the gesture actually claimed input.
This just applied to child windows, but now GDK should just take care of
toplevels, which shall get crossing events from the windowing when the right
conditions apply.
Removing this code fixes confused crossing state in widgets and messed up
window_under_pointer tracking (Which now is meant to be toplevels) when any
of the remaining child GdkWindows trigger these crossing events.
For some reason this wasn't done on windows with an impl, but it totally should.
Probably hidden by grabs in menus and somesuch being done on a child window.
We already issue the first _get_parent call before even entering that
loop, so make sure `parent` is not NULL. This happens when event_widget
is already a toplevel, and this change fixes row-dragging in treeviews.
Drop the in_widget flag since motion events the listbox receives are
always inside the listbox. Also drop the manual coordinate translation
code using GdkWindows.
We don't draw or size-allocate the titlebar when the window is
fullscreen or undecorated, so reflect this by setting it to
!child_visible. This can happen when changing the value of the decorated
property while the window is shown.
Instead of delegating on the parent shell of a menu item/shell on a variety
of situations, Simplify event handling so:
1) Menu item selection is handled entirely on GtkMenuItem through crossing
events.
2) The deepmost menu shell handles clicks inside and outside of it.
This avoids the rather hard to follow gtk_widget_event() calls going on all
throughout the handling of crossing and button events, and makes menus work
again.
As event->any.window is the toplevel, this is not useful anymore to
determine the window/widget that is the target for this event. Add
helper functions to attach user data to GdkEvents so the target
widget can be stored on the gtk/ side.
These calls should be made private with the rest of GdkEvent related
API.
It's not necessary anymore for clipping nor receiving events. So just
remove it. The event handling code was expecting events in bin_window
coordinates, and have been updated to relying on widget-relative coords.
